Di perusahaan saya, ketika saya masuk ke beberapa server, login terakhir saya dan spanduk besar ditampilkan:
me@my-laptop$ ssh the-server
Last login: Mon Feb 8 18:54:36 2016 from my-laptop.company.com

me@the-server$ Tentu saja, saya tidak ingin spanduk besar ini ditampilkan setiap kali saya masuk, tetapi saya ingin agar waktu masuk dan host terakhir ditampilkan .
Jika saya menggunakan touch ~/.hushlogin, spanduk tidak ditampilkan tetapi saya juga kehilangan
informasi login terakhir . Bahkan, tidak ada yang ditampilkan sama sekali:
ssh the-server
me@the-server$Bagaimana cara menghapus banner tetapi tetap menggunakan waktu login dan host terakhir, seperti ini:
ssh the-server
Last login: Mon Feb 8 18:54:36 2016 from my-laptop.company.com
me@the-server$
last -w | grep "$USER" | head -n1 | perl -lane 'END{print "Last login: @F[3..6] $F[8] from $F[2]"}'karenalastlogmemotong nama host saya.
